A data trading system based on a block chain and an implementation method thereof

Abstract

The invention discloses a data trading system based on a block chain and an implementation method thereof. The invention comprises a data collector, a background application management module, a blockchain data storage module based on a federation chain, a block chain data transaction module based on a public chain, and a user display terminal. The data collector interacts with the background application management system, The block chain storage module stores the data obtained by the collector in a distributed manner, and the block chain data transaction module stores the information and transaction information exchanged between the data collector and the background application management system in a decentralized manner and controls the transaction flow, and the user operates the user display terminal. The invention can encourage data providers to participate in data flow and reduce data acquisition barriers, protect the rights and interests of data providers and make full use of data value. It solves the contradiction between the high efficiency of data transaction and the high cost of current block chain. Data pricing strategies are implemented in a more concise, efficient, and executable manner.

Description

technical field [0001] The invention relates to the field of information management, and proposes a blockchain-based data transaction system and an implementation method thereof. Background technique [0002] Data is an important factor of production in the information age. In the DT era, more data value needs to be tapped. However, for enterprises, scientific research institutions and technology developers, the current data storage and utilization have the following two problems: On the one hand, mastering data concentration is too high. A large amount of data is in the hands of some Internet giants, so these Internet giants decide how to use user data, and it is difficult for small and medium-sized organizations to participate; on the other hand, due to privacy issues in the data mining process, it is difficult to discover a lot of valuable information and exploit. In addition, for data owners, due to the lack of safe and effective data transaction methods, the value of ...

[0002] Data is an important factor of production in the information age. In the DT era, more data value needs to be tapped. However, for enterprises, scientific research institutions and technology developers, the current data storage and utilization have the following two problems: On the one hand, mastering data The concentration is too high

[0004] However, blockchain technology still has some limitations, such as: how to ensure the security, transparency, and efficiency of data transactions, reduce the cost of using blockchain technology for data transactions, and reduce the size of data blocks; how to support users with large blocks Upload data, the above problems are difficult to find a good balance mechanism through the existing blockchain technology
